> People who don't understand relational theory can't write SQL to save their lives.

Source?

From anecdotal experience, I've seen countless developers write reasonably acceptable SQL without even knowing relational algebra exists in the first place.

I think if they write decent SQL, they probably understand much of relational algebra, just not the standard notation and jargon.

Like a musician who can't read sheet music.

Relatedly, my experience is that learning relational theory and SQL first makes it harder to learn Microsoft Access.

I'm afraid that the converse might be true too, so I consider this to be a negative point for Access.
